Print Time & Machine Hour Estimation
Print time is the exact duration required for a 3D printer to execute a job from initial homing and bed heating to final cool-down. In commercial quoting, print time multiplied by an hourly machine rate covers electricity, maintenance, depreciation, and shop overhead.
Factors Determining Print Time
Print time is governed by total part volume, layer height, infill density, wall line count, maximum acceleration/jerk limits, travel speeds, and the number of AMS multi-color filament changes.
Calculating Hourly Machine Rates
A standard hourly rate ($1.00 to $4.00/hr) is calculated as: (Printer Purchase Cost ÷ Expected Lifespan Hours) + Electricity Cost/hr + Maintenance/hr + Facility Overhead.
Batch Time Optimization Formulas
Printing $N$ items simultaneously on a single build plate is faster per unit than printing them individually, because bed heating, leveling, and purge sequences occur only once per run.
